D'Anthony Hopkins of Cureo, Tex., and Michael Daniel of Brookings, S.D. are new three-stars who fill out the final two spots in the initial ranking.

Wide receivers

Notable riser:Miles Boykin, New Lenox (Ill.) Providence Catholic (Up 18 spots)
Notable dropper:Jazz Ferguson, St. Francesville (La.) East Feliciana (Down 13 spots)

Tight ends

Notable riser:Hale Hentges, Jefferson City (Mo.) Helias (Up 4 spots)

Comments: This is another huge position group, but like wide receiver, there are no new four-stars in the bunch. Several of the four-stars in the group, like Petitbon and Martez Ivey of Apopka, Fla., did see their stocks raise slightly, but the top 30 on the list undergoes few changes. The highest debut is at No. 31, where Montverde (Fla.) Academy's Abdul Bello checks in as the highest ranked three-star prospect.

Offensive guards

Notable riser:Lester Cotton, Tuscaloosa (Ala.) Central (Up 6 spots)

Hylton's Matthew Burrell Jr. migrates over from offensive tackle to debut at No. 7. Alabama commit Dallas Warmack also makes a positive move after earning his fourth star, while Owings Mills (Md.) McDonogh's Ellis McKennie is the highest ranked new addition that has not moved over from another position, checking in at No. 20.

Centers

Notable riser: None
Notable dropper:Marvis Brown, Orange (Tex.) Little Cypress-Mauriceville (Down 1 spot)
Comments: Brown's drop from a 5.7 to a 5.6 rating is the only change in this position group. He trades places, then, with Honolulu (Haw.) St. Louis' Fred Ulu-Perry, who takes over the No. 4 spot while Brown ends up at No. 5.

Weakside defensive ends

Notable riser:Josh Sweat, Chesapeake (Va.) Oscar Smith (Up 4 spots)
Notable dropper:D'Andre Walker, Fairburn (Ga.) Langston Hughes (Down 7 spots)

Defensive tackles

Notable riser:Kahlil McKenzie, Concord (Calif.) De La Salle (Up 11 spots)

Cleveland's Sterling Johnson makes the highest debut on the list, checking in at No. 22. He is one of four new 5.7 three-stars added to the ranking.

Inside linebackers

Notable riser:Leo Lewis, Brookhaven, Miss. (Debuts at No. 2)
Notable dropper:Johnathon Sutton, Swansea, S.C. (Down 2 spots)
Comments: Lewis went from unranked to a four-star and inside the national top 100. His addition bumps Cameron Smith of Granite Bay, Calif., down from No. 4 to No. 5, even though Smith actually raised his stock during this evaluation period and is now rated 5.9. The second-highest debut belongs to TCU commit Semaj Thomas of Forth Worth (Tex.) Southwest, who checks in at No. 11.

Outside linebackers

Notable riser:Roquan Smith, Montezuma (Ga.) Macon County (Debuts at No. 5)

Mater Dei's Ben Humphreys and Tevon Coney of Palm Beach Gardens (Fla.). All rank inside the top 20. Williams was joined by Missouri City (Tex.) Ridge Point's Cameron Townsend as prospects from the previous top 10 who drop, but both remain among the top 13.

Cornerbacks

Notable riser:Isaiah Langley, Pleasanton (Calif.) Foothill (Up 7 spots)
Notable dropper: None
Comments: The cornerback rankings saw a ton of new talent enter the list after this evaluation period, with Pflugerville (Tex.) Hendrickson's P.J. Mbanasor debuting the highest at No. 24. He is joined by Pasadena (Calif.) Muir's Taeon Mason as new four-stars in this update. The only changes in the top 10 were Hogansville (Ga.) Callaway's Terry Godwin moving out to the athlete position and Plantation (Fla.) American Heritage's Tarvarus McFadden and Long Beach (Calif.) Poly's Iman Marshall swapping the Nos. 3 and 4 spots, with Marshall now checking in at No. 3.

Safeties

Notable riser:Rashad Roundtree, Evans (Ga.) Lakeside (Debuts at No. 1)
Notable dropper: None
Comments: While no one from the previous ranking saw their stock drop in this update, a ton of new names enter the list. Roundtree makes his debut as the top ranked safety in the country and earns five-stars right off the bat. Jordan Colbert of Griffin, Ga., is the only new four-star, but there are a ton of new three-stars. The list also grows from a ranking of 25 to a ranking of 35, so 10 new names enter theranking while all 25 from the previous list remain.

Athletes

Notable riser:Ryan Newsome, Aledo, Tex. (Up 14 spots)
Notable dropper: None
Comments: The athlete position usually sees a lot of names move in and out to other positions, and that was certainly the case in this update. The top five adds Goodwin, who debuts as the No. 1 ranked player at the position, but loses Gibson to dual-threat quarterback. Madison (Ala.) Academy's Kerryon Johnson moves up from 5.9 to. 6.0 and takes over the No. 4 position on the list. The rest of the moves happen in the bottom half, where Newsome and several new three-stars make an appearance.
